Hallo Mariyn, thank you for your query.
The complaint you have is due to reflux of acid from your stomach into the oesophagus , this also causes acid fumes to rise which can irritate the eyes and mouth. This is not a direct effect from your medication although they may aggravate the situation , by reducing the time it takes for you stomach to empty. Obviously you are on the medication for a good reason and by discontinuing you may suffer more grave problems. Having said that it might be worth trying different drugs in the class to reduce your side-effects. I suggest you try a drug called Galvis in the place of Metformin
, as Metformin is well known for gastric side-effects. Another possibility is to use an antacid
to prevent the reflux (so called GORD). Please understand that your doctor is treating life threatening conditions, and therefore you must work with him to find an acceptable treatment plan. I trust this information helps you to find a solution. Kind regards.
